covnn FOR LAUNDRY-TUBE.

Application filed June 19, 12315.

To all whom it may concern:

Be it known that we, MonRIs MALAWISTA and lVoLr SILBERMAN, citizens ofthe United States, residing at Brooklyn, county of lxings, and State ofNew York, have invented new and useful Improvements in Covers forLaundry-Tubs, of which the following is a specification.

This invention relates to the method of constructing metal laundry tubcovers whereby the jointed plates are locked together and require nosolder to make a perfect water tight closure.

The invention is essentially designed to form a cover consisting of twogalvanized metal plates, the object being to unite the plates so thatthe back of the cover will have no projecting parts or crevices for thelodgment of water or dirt. These tub covers are usually made ofgalvanized sheet iron owing to its lightness and cheapness. Heretoforethe upper and lower plates have been fastened with solder. This is veryobjectionable for the reason that the solder does not hold well on thegalvanized iron and soon comes off. When the solder comes off, thegalvanized plates buckle or bend and the cover becomes useless. As willbe here inafter pointed out, my invention consists in securing theplates by means of flanges so that it is entirely unnecessary to use anysolder. In addition to dispensing with the solder, the construction ofmy fastening device is such that the lower plate at all times holds theupper plate in a perfectly firm and rigid position and buckling isimpos-- sible.

The novel features of the invention are more fully described in thefollowing specification and claims and illustrated in the ac companyingdrawing in which:

Figure 1 represents a perspective top view of a cover embodying thisinvention. Fig. 2 is an inverted top perspective View of the same. Fig.3 is a horizontal section taken along the line 00 a: of Fig. 1 on alarger scale.

Fig. f is a view of the top blank.

In this drawing the letter a designates a wooden frame which serves as amedium for the core or foundation of the cover. On this frame isarranged a galvanized sheet metal plate I) having a depression 0 locatedin the top of the plate. This plate is bent over the rim of the frameand it has a double portion cl at its lower end. A plate 6 consti-Specification of Letters Patent.

tutes the back of the cover. This plate has corresponding doubled endportions f for engagement with the portions d whereby the plate isunited to the top. In this eon struction each plate has a fold and onelaps around the edge of the other to interlock the plates.

The frame a is provided with a channel 9 extending about the back of theframe so that when the lapped joints are pressed together they will sinkinto the channel so as to leave a flush joint h at the outer folds ofthe plates. It will be seen that by jamming the laps into the channelthe back of the cover where it sets over the frame will be entirely freeof obstructions thereby obviating the lodgment of any foreign matter andfacilitating cleaning of the cover.

As indicated in Fig. 2, the back plate is provided with a series ofcrimps 71 adapted for engagement with the depressions in the back of theframe, for reinforcing the plate, and at the same time preventingmovement of the plate.

The forward back portion of the cover is provided with the usual elasticbufiers and the top of the cover has holes is for mounting the hingebutts whereby the cover can be mounted onto a laundry tub.

In Fig. 4: is shown a blank I) of suitable shape for forming the top ofthe cover. The inner dotted lines m in this figure denote the portions02 of the flaps which are bent about the rim of the frame and the lines0 of bending for the lapped joint. Two of these flap members have wings79 projecting from the mitered part 9 of the plate and adapted when theplate is fitted on to the frame to be bent over' an edge of the rim andfastened by a clout nail as indicated in Fig. 52, thereby preventingshifting of the plate relative to the. frame.

We claim:

1. A cover of the kind described, comprising a frame, a top and backplate arranged on the frame, each having corresponding lappedinterlocking portions parallel with the frame. whereby the plates areunited.

2. A cover adapted for use with laundry tubs, comprising a frame, a topand back plate arranged on the frame each having double portions lappedaround the edge of each other located along the back parallel with theframe for uniting the plates.

lltll 3. A cover adapted for use with laundry tubs, comprising a frame,a top and back plate arranged on the frame, and means includingcorresponding lapped portions on each plate parallel along the back ofsaid frame to lie flush with the back plate for interlocking the plates.

4. A cover adapted for use with laundry tubs, comprising a frameprovided with a channel, a top and back plate arranged on the frame,each plate having double portions lapped around the edge of each otherfor uniting the plates, said uniting portions being sunk into thechannel.

5. A cover adapted for use with laundry tubs, comprising a frameprovided with a channel, a top and back plate arranged on the frame,each plate having double por-- tions lapped around the edge of eachother for uniting the plates, said uniting portions being sunk into thechannel, and one of the Copies of this patent may be obtained. for

plates having wings for engagement with the rim of the frame.

6. A cover adapted for use with laundry tubs, comprising a frameprovided with a channel, a top and backplate arranged on the frame, eachplate having double portions lapped around the edge of each other foruniting the plates, said uniting portions being sunk into the channel,the front plate having wings for engagement with the rim of the frame,and the back plate being provided with crimped portions for fasteningthe plate to the back of the frame.

In testimony whereof we have hereunto set our hands in the presence oftwo subscribing witnesses.
